The reaction force to the gravitational force acting on your body as you sit in your desk chair is the normal force exerted by the chair on your body. It is equal in magnitude and opposite in direction to the force of gravity, balancing the forces and keeping you in equilibrium.
When you sit in a chair, the action force is the downward force you exert on the chair due to your weight. The reaction force is the upward force exerted by the chair on you, supporting your weight and keeping you from falling to the ground.
The reaction force to the downward push of Billy's weight on the chair is the upward force of the chair pushing back on him. The downward force of Billy's weight on Earth is countered by the upward force of gravity acting on him.
When a person sits in a chair, the main forces acting on them are the gravitational force pulling them downward towards the Earth and the normal force exerted by the chair pushing them upward to counteract gravity. Frictional forces between the person and the chair also play a role in keeping them seated comfortably.
When you are sitting in a chair at rest, the forces acting on you are balanced. The force of gravity pulling you downward is balanced by the normal force of the chair pushing upward against you. This balanced force keeps you stationary in the chair.
The following analysis holds while I am sitting in/on the chair: Gravitational force -- downward Resistance force of the chair -- upward Sum of the forces on the seat of my pants -- Zero Therefore neither I nor the seat of my pants is accelerated.

That's because the gravitational force isn't the only force acting, in this case.

The gravitational force acting on the planet is much greater than the gravitational force acting on the moon due to the planet. This is because the planet has a significantly larger mass than the moon, resulting in a stronger gravitational pull on the moon towards the planet.
Your weight pushing down on the chair is the action force. The reaction force is the force exerted by the chair that pushes up on your body
The mass of the object the force is acting on, and the gravitational acceleration where the force is acting. F = m*g, where F is the gravitational force, m is the mass of the object and g is the gravitational acceleration (on Earth it is about 9.81ms-2)

When a person is sitting still in a chair, the action and reaction forces meet along his bottom. The 'action' is directed downward and is the person's weight, the result of the gravitational attraction between the Earth's mass and the person's mass. The 'reaction' is directed upward, and is the force developed in the structural materials of the floor and the chair. Since the action and reaction forces are equal and opposite, the net force on the person's bottom is zero, and he does not accelerate vertically.
